Abstract:
Aim: The aim of the ERUPT (Evaluating the Rate of Undiagnosed Type 2 diabetes in Patients (ERUPT) referred for Coronary Angiograms) study was to evaluate the prevalence of known and unknown dysglycaemia in those attending for outpatient coronary angiogram at Auckland City Hospital over a six month period. Design: This is a prospective, observational study design to capture quantitative data to describe the population attending for outpatient angiography and to ascertain the prevalence of existing known, as well as undiagnosed diabetes and pre-diabetes. Method: 300 participants were reviewed between September 2014 and March 2015, 277 were included. Those without known diabetes or pre-diabetes were invited to consent to the ‘tested arm’ which included an HbA1c to assess for diabetes (n=96). A further 181 participants were included in the ‘audit arm’ to ascertain prevalence of dysglycaemia overall. Results: Dysglycaemia was present in 41.6% of participants, with approximately one in five having diagnosed type 2 diabetes. 11% had known pre-diabetes and a further 10% had previously unknown pre-diabetes. Those that were undiagnosed were more commonly male, NZ European, normotensive patients who had never smoked. Those that had not had an HbA1c test in the previous 12 months were more commonly male, NZ European and had never smoked. Conclusion: Undiagnosed pre-diabetes is more prevalent in NZ European and NZ Maori patients with NZ European males the least screened group.
